[Methods] Effects of in- teraction between density and nitrogen rate on the growth and yield of direct sowing rapeseed under no-tillage condition were investigated with Chuanyou 58 as materials and a split-plot experiment adopted. [Results] In Chengdu Plain, the yields of rape- seed changed from increasing to decreasing with increase of density and nitrogen rate. Both of density and nitrogen rate had significant effects on growth and yield of rapeseed and the latter overweighed in the effect. In addition, interaction of the two had negative effects on rapeseed yield. The yield of rapeseeds achieved the highest at 3 395.25 kg/hm^2 with interaction of density at 30.00×10^4 plant/hm^2 and nitrogen rate at 180.00 kg/hm^2; the theoretical maximal yield was 3 403.41 kg/hm^2 with interaction of density at 40.80×10^4 plants/hm^2 and nitrogen rate at 198.90 kg/hm^2. [Conclusion] In Chengdu Plain, the optimal density and nitrogen rate are 30.00×10^4-45.00×10^4 plant/hm^2 and 180.00-198.90 kg/hm^2, respectively.展开更多

METHODS： Transplantable murine hepatoma22 （H22） model was used to evaluate the effects of social isolation stress on murine liver cancer. Mice were immunized with sheep red blood cell （SRBC） and intraperitoneally inoculated with H22 cell, then divided into two groups, one reared individually as group （I） and the other reared in groups as group （G）. Titer of antibody to SRBC and interleukin 2 （IL-2） in serum was monitored. The survival time of mouse with liver cancer was observed. RESULTS： The titer of antibody to SRBC in group （G） was 1：24.5 and that in group （I） was 1：11.2. There was a significant difference between these two groups （t = 2.60, P = 0.02）. A significant difference in IL-2 concentration was observed between group （G） （39.6 ng/L） and group （I） （47.1 ng/L, t = 2.14, P = 0.046）. The survival time in group （G） （16.5 d） was markedly longer than that in group （I） （13.2 d, t = 3.46, P = 0.002）. CONCLUSION： Our study suggests that survival time of the mouse bearing H22 tumor is affected by the social isolation stress and the associated mechanism may be the immunological changes under the social isolation stress.展开更多

This expansion involves a general combination of a regular wave, a wave source, a wave dipole and a regular wave-free part. The wave-free part can be further expanded in terms of wave-free multipoles which are termed as wave-free potentials. These are singular solutions of Laplace's equation (for non-oblique waves in two dimensions) or two-dimensional Helmholz equation (for oblique waves) satisfying the free surface condition and decaying rapidly away from the point of singularity. The method of constructing these wave-free potentials is presented here in a systematic manner for a number of situations such as deep water with a free surface, neglecting or taking into account the effect of surface tension, or with an ice-cover modelled as a thin elastic plate floating on water.展开更多
